If you do a lot of shooting with an AR-15, this is a must-have tool. Loading single rounds into twenty or thirty round magazines is never fun and takes away time from shooting. The engineers at Caldwell must have felt the same way, which is probably why they designed this tool.

The Mag Charger will accept .223 Remington, 5.56mm NATO and .204 Ruger ammunition and is compatible with all AR platform mags, including mil spec and molded plastic magazines. It enables you to load 50 rounds from any factory box or aftermarket plastic storage box into two magazines in 15 seconds or less. That is pretty impressive.

The simplicity of design is what makes the Mag Charger so efficient and easy to use. Simply align the bullet tips with the Charger and dump them in. You don't have to handle a single round individually.

Once the Charger is loaded, insert your AR magazine, just as you would into your rifle, and slide the plunger back and forth. It loads five rounds with each stroke. Continue until the magazine is full, insert another magazine and load the remaining rounds.

In case you have ammunition that comes in boxes with the bullets pointed down, the Charger comes with an Ammo Transfer Tray that allows you to invert the cartridges and then load them into the Charger. The only ammunition boxes that will not work are those that grip and separate each round in rigid plastic carriers. However, these rounds are generally high-end premium rounds and not normally used for plinking.

The Mag Charger is constructed from a very tough polycarbonate material. It should provide years of use under normal conditions. With an MSRP of $89.99, the Caldwell AR-15 Mag Charger is not for everyone. However, if you are a regular AR platform shooter, this tool lets you spend more time shooting and less time loading.
